I don't want to popularize Song ID as a field that users should use for display or sorting purposes, as it overrides the matching logic when using the library synchronization feature, as well as the sharing features (and optionally the Connect Tablets feature). I'm actually considering renaming it to "synchronization ID" so that people understand it's not just a simple identifier, and also hiding it by default, because I'm finding many users are using it like another piece of metadata and then running into major synchronization issues because of it.
